I hope we're not going to repeat the metalinguistic argument over
the meaning of the word "support."  An electric power cable can be
used as a tool by a programmer to write code to support dynamic typing.
(I'm using several such cables to write a Usenet article too.)
But the programmer is writing the code to do the support.  The
cable itself does not do the support.  A pencil does not support
software design the way some CAD products do.

If this were the company's opinion, I wouldn't be allowed to post it.
